Most frequently asked question:
"Can you talk to my family for me?" (Just kidding... kind of) But really, the number one question I get is: Do I have to give an "and guest" to a single person?"
This comes up with almost every friend (and every client) who is hosting a party. I generally air on the side of no plus one, but I think it's really a matter of judgement. If you are having a wedding, with lots of single friends, I'd say no plus one. If you are inviting a single person, who is really not friendly with others attending, I'd give them a plus one if space and budget allows.
